Can you update patch-src_llvm-project_compiler-rt_lib_builtins_cpu__model.c with what will probably be committed upstream : https://reviews.llvm.org/D109330 . I've put the updated file on freefall.
In lang/rust-bootstrap: we can remove the llvm90 dep for aarch64 with the following patch:

FYI, Cargo has an (unstable) --out-dir option we hopefully can set in the future which lets us configure the directory for the final build artifacts. Then we don't need to do stuff like this to find them.

Any idea what could be broken?

The bootstrap compiler passes a simple smoke test for me (in a ppc jail in a qemu-system-ppc64 vm; all on FreeBSD 13.0-RELEASE). I can build and run a simple hello panic program. Does this work for you?

[pkubaj]

Yes.

root@powerpc-130-rust:~ # vi hello.rs
root@powerpc-130-rust:~ # /wrkdirs/usr/ports/lang/rust/work/bootstrap/bin/rustc hello.rs
root@powerpc-130-rust:~ # ./hello
Hello World!

I noticed that cargo segfaults:

root@powerpc-130-rust:~ # ls /wrkdirs/usr/ports/lang/rust/work/rustc-1.55.0-src/cargo.core
/wrkdirs/usr/ports/lang/rust/work/rustc-1.55.0-src/cargo.core

pid 61878 (cargo), jid 239, uid 0: exited on signal 11 (core dumped)

This is probably the reason why build fails.

[tobik]

• lang/rust-bootstrap: Use devel/freebsd-sysroot
• lang/rust: Bump powerpc bootstrap to 1.55

I was able to reproduce the cargo crash on powerpc but not sure why
it happens. Anyway bumping the powerpc bootstrap to a new 1.55 one
let's the build go further, but the qemu vm is too slow to let it
finish completely. Can you check if a full build works now?

[pkubaj]

Ok on powerpc, still have powerpc64le to test on.

@mikael Should I update the armv7 bootstrap with the new ones from https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257419#c25 ?

Yes, and the armv6 one please (same location). Thanks a lot!
